SPECIFICATION forming part of Letters Patent No. 627,718, dated J une27, 1899.

Application filed May 2, 1899. Serial No. 715,344. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT H. CHAPMAN, a citizen of the United States,residing at Washington, District of Columbia, have invented a new anduseful Genealogical Skeleton Chart, of which the following is a specification, reference being had to the accompanying drawings. 7

My invention relates to the collation and graphic arrangement of thedata of ancestors by generations.

It is my object to furnish some base or form for the student orcollector of genealogical facts that will aid him in the arrangement ofthe memoranda he desires to record, so as to present to him a continuouscomparative record.

The continuity of my chart will enable the investigator to arrange hisstatistics in uninterrupted and consecutive order. The arrangementenables the student to .see at a glance the number, name, andcompleteness of record of his ancestors in any given generation. r

To this end I have invented a chart on the segment of a circle or othercurved figure, on which the student or collector may write or otherwiserecord the names, dates, or other facts relating to individualancestors, together with the relationship which each ancestor bears toeach preceding and succeeding generation.

More particularly describing the same, my chart or diagram is laid outwithin the area of a segment of a circle or other curved figure. Withinthe outer area and generally parallel to the circumference curved linesare drawn in gradually-diminishing arcs, dividing the total. area into anumber of segments of rings or zones, each of which is to receive therecord of a single generation of ancestors, Radially from the center oran approximately central point a line is drawn to the, circumference,dividing the area into two parts. These twoparts are again divided by aradial line drawn from the circumference toward the middle point, butnot to it, and ending at the outer perimeter of the first segment,counting outward from the center. The resulting four parts are againdivided by radial lines from the circumference toward the center, butending in the outer circumference of the second segment, counting fromthe center outward. Similar division of spaces is continued until theresulting spaces are too' narrow to permit of the recording of names ofancestors between the radial lines or until the last or outer segment isdivided. 1

Having thus described my invention, I claim A genealogical skeletonchart or diagram comprising a sheet of paper or other material, havingthereon a series of concentric lines or arcs crossed by series of radialstraight lines, each successive series of said radial lines terminatingat the are next succeeding the are at which the preceding series ofradial lines terminates, substantially as described.
